What I do

Native iOS development, senior end to end

iOS App Development

Native Swift and SwiftUI development for new and existing products.

Existing App Development

New features, architecture improvements, bug fixing, modernisation and getting delayed projects shipped.

AR & 3D

ARKit, RealityKit, SceneKit, LiDAR, 3D model interaction, raycasting and immersive iPhone experiences — see the specialism.

MVPs & Prototypes

Helping founders turn ideas into polished, working iOS products quickly.

Product Engineering

Product management experience alongside engineering, so I contribute to UX and product direction, not just specs.

Expertise

Swift, SwiftUI and Apple's frameworks

I write native iOS apps in Swift and SwiftUI, covering the full lifecycle: architecture, UI, networking, persistence, App Store submission and the updates that follow. 12+ years building for iPhone means I've worked across UIKit-era codebases and modern SwiftUI apps alike, and I'm comfortable moving between the two.

AR and 3D is a strong specialism within that: ARKit, RealityKit and SceneKit work anchoring 3D content in physical space. If your brief involves 3D models, object placement or camera-based interaction, that's a dedicated part of what I do, not a side interest.
